Tag history

Free, but ad-supported

Once a song is identified, or "tagged" as Shazam calls it, you can listen to it on Rdio (if installed), see a discography of the artist, find ringtones on a third-party site, or watch YouTube videos of the song. There's even an option to jump over to Amazon and purchase the song.
